Hi

Looking for some help ..... I was given a pair of Stax SR-Lambda Pro Ear Speakers.... looks like there were minimally used. In orderfor me to test them i need a electrostatic amp for it.... Does anyone on the group have a amp I can try ? or other suggestions?

thanks
Bill
Hi,

If you are in SoCal, I could help, not sure how well my amp will ship. But I don’t think you are.
There are adapter boxes that plug into an amp, you could use one of those, but they are normal bias. That would give you a yes/No for operation. If you find the radio shack one, they are wired differently, and will give a mono sound with Stax headphones.

"It’s basically my Dad’s fault" lol!

I'd venture to guess that I am a wee bit older than you, as my interest in audio began in the 1970s. I grew up in Evanston, IL, just north of Chicago, and was lucky enough to have access to a really good, and then rather uncommon Hi-Fi store called Audio Consultants. I loved to hang around and listen to the components, even though it would be a few years before I could afford anything remotely high-end. I learned plenty from the salesmen during that time, and a passion was born.

Some of the notable early components that I once owned were an Apt-Holman pre-amp, Dalquist DQ10 speakers, an early Bryston 4B amp, Magnepan Tympani speakers, Nakamichi 600 cassette deck, Bang & Olufsen Beogram 4000 (vertical tracking) turntable, and the list goes on.

In recent years I developed a fit for purpose system that suited my smaller space in Lisbon, including a vintage, re-capped Accuphase E-303x integrated amp, matching T-103 tuner, Electrocompaniet EMC-1IP CD player, and Harbeth P3ESR speakers.

I build a lot of my own gear nowadays, but here's what we listen to en famille...

The Mac MC275 is my all time favorite grail piece but I keep spending on other pieces that catch my eye....squirrel!....I will one day stop with the gear collecting/swapping and finally order one up.

Just beautiful

I've gone through many stages in putting together my audio reproducing system. I taught electronics for many years and used audio components to keep the students interested.
These are 3 of my favorite systems from the last 35 or so years.


This last one is my current system and my most satisfying for as close to live music reproduction I've achieved. My SO is a Jazz singer and Musical Theatre performer so, I have many opportunities to judge how it sounds and even as good as it can get, live is still the goal.

Not a rational decision but I had a pitch or keep call to make. It was fried. I decided, having owned this thing forever that I’d have it redone. Here it is driving some massive JBL Studio Monitors at the repair shop today. Asia of course was the test song. Will build a third system in my basement. Vintage with a USB table. It’s an interesting shop btw.

i took a full stop on watch hunting and opened the hifi season. experimented a lot with passive and active roomacoustics

so for the moment my systems sound decent on streaming , TV and gaming

speakers are spatial europe No3 open baffle driven by an gamut D200 amplifier (2x custom monoblocks with a mix of hiraga and pass first watt whooping 24W class A as fallback amps) fed by a custom build dual mono DAC

DIY guys with a special call out to @JwRosenthal and @Bill Sohne …. I suspect I’m going to need to lay in a supply of these. They appear to be the Achilles heel of 70s vintage audio. Do you folks know of a serious supplier who does not deal in cheap knockoffs? Many thanks.

I have a tech friend who hoards vintage parts (for this exact reason) including bumble bee caps. I can reach out to him and see if he has that one- provided that is the Darlington you need and not a stock photo.

Thanks.. the one my guy salvaged from a donor failed. I’m sure he can get another but I’d like a few since they seem to be this units Achilles heel. The photo I posted came out of my reciever.

Well this little “vintage” project got out of control quickly. My SA400 is back with another Darlington chip at no charge. I had to confess that I put my multimeter on the speakers I was gonna use and they were the culprits. Yes, I rebuilt em. After i was instructed to “beat the living s..t out of” the Technics driving Dark Side O.M. over the shop pro JBL’s (See earlier post) , I was told to go forth and sin no more but i was reminded that his stock of Sanyo chips is finite and reserved for the 7 series Pioneers. Anyway, new AT USB table, Solidsteel rack, Panamax, and because all the vintage speakers I looked at were in need of major surgery, some scratch and dent JBL L82’s from good ole Crutchfield. (“you do know those are not real JBL’s” my repair guy said as we tossed back some booze over the debrief), a fistful of evergreen interconnects, 12 gauge wire and bananna clips, speaker stands arriving tomorrow. Looks like another watch will need selling. This repair shop is so much fun, I wish I had more crap to get fixed. Its great running my vintage Sony cassette deck again. Huge win…My wife cannot hear this system in the bedroom unlike the Rotel/B&W zones.

Every audio vintage gets out of hand quickly. The rabbit hole has no end, period vintage or other wise. Too late for u.
